Ah, thanks Pali.
Mauri, please let us know what your plans are with Orion5 support in
mainline U-Boot. Without a board using the code its practically dead and
will be removed completely soon. But if you have plans to add at least
one Orion5 based board to mainline then this is very welcome of course.
Thanks,
Stefan
